Cell test results

Tyrosine kinase activity was measured using the synthetic Src peptide substrate NH2-RRRAAAEEIYGEI-NH2, while the enzyme was a GST fusion of the intracellular domain expressed in SF9 cells. Testing results are provided in Table 1. 

Analyzing the minimal inhibition concentration (MIC) data for nine different strains, resulted in two significant PCs being obtained, accounting for 77.1% and 16.1%, respectively, of the data variance. Thus, the intrinsic dimensionality of the data matrix of nine assays was only two. The loading plot, that is, a plot of the calculated PCs with respect to the descriptors, shows that the first component is mainly related to the seven cell-free test systems, while the second component represents the two whole-cell test results. Thus, there was much correlation between the results of the seven cell-free assays and the two whole-cell assays were correlated with each other but not with the cell-free assays. In other words, much redundant information was obtained... 

For the fine-gradient ELAT , we first establish the relationship between ink formulation parameters and how they impact key architectural quantities such as pore size distribution and hydrophobicity. Next, the architectural quantities are linked to actual fuel cell test results. Finally, fine gradients of porosity and hydrophobicity are constructed using the relationship(s) previously established. 

Ir- and Rh-based catalysts have been investigated for ethanol oxidation reaction in acidic media, and there have been some interesting and reasonably promising results [116-118]. Lamy et al. [116] carried out in situ FTIR study on poly crystalline Ir and Rh electrodes and showed ethanol oxidation on Ir leading selectively to either acetic acid or acetaldehyde, while Rh is abetter catalyst in the total oxidation of ethanol to CO2. Cao et al. [117] studied carbon-supported IrsSn nanoparticle electrocatalyst, and the fuel cell test results showed that the overall performance of Ir3Sn/C was comparable to that of the PtsSn/C catalyst.

The proton conductivity of PFSA depends on the membrane s relative humidity (RH) or the water content. Figure 1.9 shows that Nafion conductivity increases with increasing values of RH or water content. PEM fuel cell testing results have also indicated that membrane conductivity increases with increasing RH [67]. The temperature can also affect proton conductivity. 

Figure 2.12 shows SEM micrographs of the GDL surfaces with MPLs prepared using different carbon powders. It can be seen that the MPL with AB possesses rich pores and a uniform surface, whereas the MPL with BP is dense and has only large cracks. These features can be attributed to the properties of AB and BP carbon powders, which have been addressed in Section 2.2.1.2. As shown in Fig. 2.12, an MPL with composite carbon powders (CC) presents a more uniform surface with finer pores. The fuel cell testing results indicate that the best performance is achieved using an MPL with CC, as shown in Fig. 2.13. This can be explained by the more functional pore structure formed on the MPL when CC facilitates the mass transport of gas and water [22,30].

It is recommended that cell test results be reported in a way that makes it easy to derive area specific resistance (ASR) from the i-V curves. Sufficient information should be provided so that the ASR values can be corrected for effects of finite fuel utilisation. Also, the choice of fuel composition should preferably reflect real cell operation conditions. The ASR should be derived using the Emf and a cell voltage in the range of 0.5-0.7 V and its corresponding current density. In case of a grossly non-linear I-V curve, a differential ASR value is of little practical use.
